摘要： Downstream synchronous multichannel (DSSM) communications are provided among a plurality of carriers, each being a completely DOCSIS™ 2.0-compliant downstream. The synchronous multichannels support communications with both DSSM-capable communications nodes and non-DSSM-capable communications nodes (e.g., legacy cable modems). Non-DSSM packets are transmitted on a single channel. DSSM packets are split into multiple pieces, which are transmitted simultaneously on all available channels. Since the physical delay variation (e.g., group delay change) across the adjacent carriers is small (on the order of a symbol time), the multiple pieces arrive at the receiving communications nodes at nearly the same time and can be reassembled with minimal buffering and no packet ordering problems. To avoid causing trouble for the non-DSSM-capable communications nodes, the packet pieces are encapsulated with a header that causes the non-DSSM-capable communications nodes to silently discard them.

摘要： Data packets transmitted over a wireless network are suppressed by hardware at the transmitting end and expanded on the receiving end. This conserves bandwidth as well as reduces the processing resource requirements in both the subscriber station and the base station. An extended header element is added to a data packet that is to be transmitted over the wireless network. The extended header element contains an index that is used along with an identifier to access a rule. The rule is used to determine which bytes are to be suppressed at the transmitter and expanded at the receiver.

摘要： A system and method for processing information transport elements, such as ethernet packets, at interfaces to a forwarder. Modules that implement processing logic are allocated per interface and per direction (i.e., inbound or outbound). At any given interface, a series of modules would be used to process inbound packets; likewise, a set of modules would be used to process outbound packets. For inbound packets, the modules allocated for inbound processing are executed when the packet is received from the interface, before sending the packet on to the forwarder. For packets that are outbound from the forwarder, the modules allocated for outbound processing are applied when the packet is sent by the forwarder, prior to any other processing, e.g., queuing to hardware. To assign modules to different interfaces at a forwarder, a registration process is performed during the system start-up process, or dynamically at runtime. For any given interface and direction, modules can be prioritized, so that a packet is processed sequentially in a specific order, one module after the other.
摘要翻译：一种用于在与转发器的接口处理诸如以太网分组之类的信息传输元件的系统和方法。根据接口和每个方向（即入站或出站）分配实现处理逻辑的模块。在任何给定的接口，一系列模块将用于处理入站数据包; 同样，一组模块将用于处理出站数据包。对于入站数据包，在将数据包发送到转发器之前，从接口接收到数据包时，执行分配用于入站处理的模块。对于从转发器出站的数据包，在进行任何其他处理（例如排队到硬件）之前，当转发器发送数据包时，分配用于出站处理的模块被应用。要在转发器处将模块分配给不同的接口，在系统启动过程中或在运行时动态执行注册过程。对于任何给定的接口和方向，可以对模块进行优先级排序，以便以特定顺序顺序处理数据包，一个接一个地进行处理。

摘要： Data packets transmitted over a cable network are suppressed by hardware at the transmitting end and expanded on the receiving end. This conserves bandwidth as well as reduces the processing resource requirements in both the CM and the CMTS. An extended header element is added to a data packet that is to be transmitted over the cable network. The extended header element contains an index that is used along with the SID to access a rule. The rule is used to determine which bytes are to be suppressed at the transmitter and expanded at the receiver.

摘要： Methods and systems for estimating available bandwidth on an internet access network are presented. A method includes: (a) transmitting one or more Internet Control Message Protocol (ICMP) echo request packets to a device residing on the network at a first bit rate; (b) receiving one or more ICMP echo reply packets corresponding to the one or more ICMP echo request packets responsive to step (a); and (c) determining a second bit rate for the one or more ICMP echo reply packets. If the second bit rate is less than the first bit rate, available bandwidth is estimated based on the second bit rate. If the second bit rate is not less than the first bit rate, steps (a), (b) and (c) are repeated. The first bit rate is increased for each iteration, until the second bit rate is less than the first bit rate, and then available bandwidth is estimated based on the second bit rate.
